freebsd stable - Feb 2006 - clock reverts to epoch on boot?

I have an odd problem... I've recently upgraded (binary) from FreeBSD 
5.4 to FreeBSD 6.0 then CVSUP'ed to STABLE (6.1 Pre-release) a few 
days ago, around February 10th it looks like (back when my time 
worked right) :). I went through the whole thing like normal, rebuilt 
world, built custom kernel, etc... I also updated the BIOS and RAID 
firmware on the server, a Dell 2650. During this update process it 
seems FreeBSD's time handling went a little crazy. Although my CMOS 
clock is correct (I can verify it by rebooting and going into the 
setup), every time FreeBSD boots, it thinks it is the beginning of 
Epoch time... I can sync it with ntp, but upon reboot it is right 
back to Epoch again. I searched the archives and couldn't find this 
exact problem... Now, I did do a lot of updates and unfortunately 
didn't notice exactly when it broke. Some programs were acting a 
little strange (BIND in particular consuming my CPU on bootup until I 
manually restart it) and my RRD databases are very confused as well 
as other programs naturally.

I *think* this started happening after I did a 
buildworld/installworld (in single user of course) but I'm not 
positive. Here is my dmesg output for my hardware:

I may try doing a cvsup of source and rebuilding again. My make.conf 
settings are pretty tame:

CPUTYPE=pentium4
CFLAGS= -O2 -pipe
COPTFLAGS= -O -pipe
NO_GAMES=true
PERL_VER=5.8.7
PERL_VERSION=5.8.7


I can't see anything out of the ordinary combing through the syslog output.

Any ideas? Any takers? :) Thanks in advance!

Remove the CPUTYPE declaration, or at least decrease it to just
"pentium".

OK, I can try that. Come to think of it, I did have it set to "p4" 
previously and I believe it was working. Why would this make a 
difference? Also, I just booted in single user mode and the clock is 
correct. Does this likely confirm it is a problem when I did a 
buildworld with that CPUTYPE set?

Nevermind. I just answered my own question. I should have RTFM more 
carefully. :)

If CPUTYPE is defined in your /etc/make.conf, make sure to use the
         "?=" instead of the "=" assignment operator, so
that buildworld can
         override the CPUTYPE if it needs to.

I am thinking if I change to

CPUTYPE?=pentium4

I will be ok. Does that sound correct or am I still barking up the wrong tree?

Thanks!!

Better use "?=".

I recommend not to overide those two at all.  Especially
your CFLAGS setting might generate broken code because
there are sources which are not aliasing-clean, which can
break with any optimizations beyond -O, unless you also
specify -fno-strict-aliasing.

The defaults are "-O2 -fno-strict-aliasing -pipe" for
CFLAGS, and for COPTFLAGS it's "-O -pipe" if DEBUG is
defined (the default in GENERIC), otherwise "-O2 -pipe
-fno-strict-aliasing".

Best regards
